Problems solved by technology

The disadvantage of the former is that the durability of the fabric is relatively low, and the service life of the clothes is relatively low; the disadvantage of the latter is that the performance of the fabric cloth in terms of air permeability and sweat absorption is not satisfactory, and it will cause discomfort when worn for a long time
In terms of fiber materials, the currently commonly used polyurethane elastic fibers have poor elasticity and wear resistance, and need to be further improved.

preparation example Construction

[0023] The embodiment of the present invention discloses a preparation method of a composite yarn, comprising the following steps: providing a polyester yarn core formed by a PET / PTT composite fiber; immersing the artificial fiber in a toluene solution of glycidyl methacrylate (GMA), Fix PGMA on the surface of the rayon by interfacial polymerization, and then graft cysteamine on the surface of the rayon; soak the rayon grafted with cysteamine on the surface for 1-5 hours in the antibacterial mother solution, wash and dry to obtain an antibacterial The artificial fiber outer sliver, the antibacterial mother solution includes titanium dioxide particles, nano-silver particles and hydrochloric acid aqueous solution; the artificial fiber outer sliver is spirally wound on the polyester yarn core to obtain a composite yarn.

[0024] As a preferred solution, the PET / PTT composite fiber is prepared according to the following method: polyethylene terephthalate (PET) and polytrimethylene ...

Embodiment 1

[0040] Such as figure 2 As shown, the pre-dried PET and PTT were placed in two melters 1a and 1b according to the ratio of 7:3 in parts by mass and heated and melted, and the temperature was set at 230°C. 2b Feed into the composite spinneret 3, the composite filament 4 that is extruded and spun passes through the stable windless zone 5, and contacts with the condensed air ejected from the cooling window 6, and the cooled filament 4 is wound to the winding roller. On the driven bobbin 9, winding yarn is formed, and a pair of guide rollers 7 and 8 are used to adjust the tension to obtain bicomponent polyester fibers, namely PET / PTT composite fibers.

Abstract

The present invention provides a preparation method of a long-lasting antibacterial and anti-crease composite yarn. According to the method, since methylbenzene has a swelling effect for polyester fibers, GMA is subjected to interfacial free-radical polymerization on the surface of artificial fibers, and generated PGMA can be anchored on the surface of the artificial fibers, and therefore, epoxy groups can be led onto the surface of the fibers; through a grafting reaction, the epoxy groups react with amidogens on cysteamine, so that sulfydryl can be led onto the surface of the fibers; stable S-Ag bonds are formed between the sulfydryl and silver particles, so that composite nanoparticles can be immobilized on the surface of the artificial fibers; and the outer yarn body of the yarn is coated with titanium dioxide / nano silver composite nanoparticles, and the durability of the antibacterial property of the yarn can be improved through the synergistic effect of titanium dioxide and nano silver particles. The composite yarn produced by the preparation method of the invention has the advantages of excellent antibacterial performance and anti-crease effect as well as favorable fluffiness, flexibility and comfort, and excellent gas permeability and moisture absorption performance, and touches soft.

Description

technical field [0001] The invention relates to the technical field of textile fabric processing, in particular to a preparation method of composite yarn. Background technique [0002] When fiber products come into contact with the human body, proper humidity and temperature provide a suitable growth environment for bacteria and fungi. As people pay more and more attention to the safety of clothing, textiles with antibacterial function have gradually become people's first choice. In addition, clothes that are easy to wrinkle require a lot of energy to take care of, and there are new requirements for the wrinkle resistance of fabrics. [0003] At present, in order to endow fiber products with an antibacterial function, zinc oxide nanoparticles are often used as an additive, blended and coated inside the fiber, and migrate to the surface of the fiber through slow release to play a bactericidal role. However, single inorganic nanoparticles have gradually been unable to meet t...
